Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738686, here are decompositions:

107 + 8738579 = 8738686
179 + 8738507 = 8738686
239 + 8738447 = 8738686
347 + 8738339 = 8738686
353 + 8738333 = 8738686
557 + 8738129 = 8738686
563 + 8738123 = 8738686
599 + 8738087 = 8738686

Showing the first eight; more decompositions exist.
